inorganic and organic compounds, primarily as a result of human activities. While inorganic pollutants occur as natural elements in the Earth’s crust and atmosphere, human activities such as industry, mining, motorized traffic, agriculture, logging, and military actions promote their release and concentration in the environment, leading to toxicity (Nriagu 1979). Organic pollutants in the envir...

Fertilizations affect soil organic carbon (SOC) content but the relative influences of the edaphic and climate factors on SOC storage are rarely studied across wide spatiotemporal scales. This study synthesized long-term datasets of fertilization experiments in six typical Chinese croplands, and calculated annual C input from crops and manure amendments, changes in SOC storage (ΔSOC) and C sequ...

BACKGROUND Forest resources supply a wide range of environmental services like mitigation of increasing levels of atmospheric carbon dioxide (CO2). As climate is changing, forest managers have added pressure to obtain forest resources by following stand management alternatives that are biologically sustainable and economically profitable. The goal of this study is to project the effect of typic...

Interactions between the terrestrial nitrogen (N) and carbon (C) cycles shape the response of ecosystems to global change. However, the global distribution of nitrogen availability and its importance in global biogeochemistry and biogeochemical interactions with the climate system remain uncertain. Based on projections of a terrestrial biosphere model scaling ecological understanding of nitroge...

carbon is the most important greenhouse element which sequestrates by photosynthesis procedure and is the easiest and cheapest way of decreasing atmospheric gas level. the vegetation cover that has woody texture is more capable for carbon sequestration. the most plant species of arid rangelands are the shrub growth forms. the purpose of this research was to assess carbon sequestration potential...

soil is known as a suitable reservoir for carbon sequestration. the objective of this study was to investigate the capability of haloxylon on sequestration of carbon in sand dunes of yahya abad, sabzevar, in northeastern iran. eighty soil samples were taken from two depths of 0-5 and 5-10 cm under and between haloxylon trees. eight soil profiles under and between haloxylon trees were described ...

Soil biological activity has important implications for soil carbon (C) sequestration. However, very little is known about the environmental factors, particularly the effect of soil mineralogy on availability of C for soil microorganisms. In this study, we have investigated the influences of soil type (clay mineralogy) on C mineralization and its effects on biological activity at different leve...

Soil quality is one of the main factors that affect growth and tea (Camellia sinensis L.) plantations. The formation organo-mineral complex critical influence evolution soil fertility. This study used chemical analyses spectroscopy to effects inorganic organic fertilizer on nutrients in garden soil. SR-FTIR analysis revealed clay minerals were connected as nuclei with capacity bind carbon, this...

Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in g...
